When I type ping -a IP of server - random mirror name is shown
i.e ping -a 192.168.1.80 returns pinging opensuse.schludtech.de [192.168.1.80] with 32 bytes of data:
if I reboot - it will probably another name
I’m assuming this is the mirror the machine is connected to for updates!
If I ping the assigned Hostname - that return the IP correctly !
NB: I have checked our SLES 15SP3 Servers at work and these all respond correctly
ie. pinging 192.168.1.7 with 32 bytes of data
I notice there a few seconds pause before anything is returned from the SLES boxes
There is an important, but not easy to find feature on the forums.

The most likely explanation for this, is that you are behind a firewall that separates you from the Internet. And on that firewall there is a proxy server which sets up proxy connections to sites that you are permitted to access.
